Review Case Reports
Traumatic pneumatoceles in an infant: case report and review of the literature.
A female infant who was run over by a tractor was admitted to an outside trauma unit. In addition to severe intraabdominal injuries, she sustained blunt chest trauma. In the right lung she developed pneumatoceles 48 hours after the trauma which were misinterpreted as pneumothorax on repeated chest x-rays. ⋯ Compression of an elastic thorax is followed by a greatly increased negative intrathoracic pressure on chest rebound and this sequence of events causes bursting lesions of the lung resulting in traumatic intrapulmonary cysts, the so-called pneumatoceles. One must be aware that pneumatoceles can develop and initial diagnosis is difficult. Although usually uncomplicated, a pneumatocele that does not progressively become smaller can be a life-threatening complication of blunt chest trauma and surgical resection is recommended.

Case Reports
Thrombosis of the arterial cannula during extracorporeal membrane oxygenation in a full-term newborn infant.
The authors report a rare case of cannula thrombosis during extracorporeal membrane oxygenation (ECMO). A full-term newborn infant was successively placed on single-cannula veno-venous extracorporeal lung support and then on veno-arterial ECMO, because of persistent pulmonary hypertension. At 140 hours of ECMO, the infant displayed general cyanosis except in the right arm. ⋯ It showed an opacification of the whole cannula but for the last distal centimeter, and of the vascular bed extending from the right subclavian artery. Cannula thrombosis was suspected and confirmed by removal of the arterial cannula. Demonstration of cannula thrombosis by opacification of the arterial line of the circuit indicates catheter removal.
